EXTERNAL WALL INSULATION /
OVERVIEW /
PermaRock external wall insulation systems have been used successfully for over 25 years in the UK and the technology applied for more than 40 years in Europe.
Suitable for new and existing buildings, amd on both low-rise and high-rise constructions, external wall insulation (also referred to as solid wall insulation) is a technology developed to improve the thermal performance of buildings (helping reduce CO2 emissions) by the application of insulation and a decorative weatherproof render to the external wall surfaces.
PermaRock systems are suitable for application in areas classified as having very severe exposure - i.e. the whole of the UK and the application of an external wall insulation system has a number of positive benefits:
- Improved insulation levels lead to a reduction in heat losses and therefore to a reduced energy demand for heating in the winter months.
- Higher levels of insulation help to reduce building overheating in the summer months, thereby reducing the energy demand for cooling.
- Reduced energy demands result in lower CO2 emissions.
- Interstitial or internal condensation on walls can be eliminated, and the attendant problems of damp internal surfaces and mould growth are overcome.
- The building fabric can be protected against the effects of the weather by the insulated cladding.
- The building structure is protected from daily environmental temperature changes. Fluctuations in internal temperatures are reduced, leading to more comfortable living and working conditions.
